I am just on my second Playthrough and I have to say...it is fascinating, going through the game again. All the little things I did not pick on, the first time around really give the game a still fresh feel. I wonder how the community feels? Did it also still feel fresh for you, the second time around?

Well I feel the game doesn't draw its replayability in a common way, like e.g. a RPG would. It's a very linear experience. The replayability comes from the knowledge you gain from your first playthrough. Suddenly many things get a different meaning e.g. right at the start in the lighthouse: A small wash basin with a sign over it reading: "Wash away your sins" and Booker refusing to wash himself. "Yeah good luck with that."

I'm in the same group that doens't find it very replayable. The combat was unmemorable to me(just a halo clone all the way down to shields and two weapon limitations, the plasmids just take the place of grenades imo). The choices had no affect at all, the atmsophere lacked the vacuum sucking that Bioshock one had that pulled me in.

All in all, I didn't really enjoy it too much the first time, I will probably play bioshock 1 though because of it.

On a second play, it is incredible, bc knowing the story, you'll pay attention to so much littlie details that you missed the first time.

I'm not sure about the 3rd though. (tho for me 99 mode will be the 3rd and I think it will be fun)

Exactly, there is a large concept unveiled towards the end which makes things that happened before it make much more sense. For example, when Robert Lutece says Booker "doesn't row" in the very beginning
